Air
pollution is contamination of the air that occur due to human and natural
action. It occurs when any harmful gases, dust, smoke enters into the
atmosphere and makes it difficult for plants, animals and humans to survive as
the air becomes dirty.
The causes of air pollution
The
eruption of volcano is the natural event that can caused air pollution. It
occurs when the smoke, dust and harmful gases release into the atmosphere.
However natural causes are not very often occur.
Volcano Mount Sinabung in Sumatra, Indonesia
erupts spewing lava and ash.
Human
activity such as burning fossil fuels will lead to the air pollution. Sulfur
dioxide emitted from the combustion of fossil fuels like coal, petroleum is one
the major cause of air pollution. We rely to
fossil fuels to fulfill our daily basic needs but the overuse of them
may leads to the air pollution that is killing our environment.
Besides, emissions
from industries and manufacturing activities also cause air pollution. Manufacturing
industries release large amount of carbon monoxide, hydrocarbons, organic
compounds, and chemicals into the air. There are many manufacturing industries
that can be found at every corner of the earth. The worst thing is all the area nearby the manufacturing
industries will be affected by the release of the harmful gases into the
atmosphere.
Agricultural
activity is one of the causes of air pollution. These happen when ammonia
release into the atmosphere. Ammonia is a very common by product from
agriculture activities and it is one of the most hazardous gases in the
atmosphere. Overuse of insecticides, pesticides and fertilizers in agricultural
activities might be pollute the air. They emit harmful chemicals into the air
and can also cause water pollution.
The effects of air pollution
Acidification is one of the effect of air pollution.Chemical reactions involving air pollutants can create acidic compounds which can cause harm to vegetation and buildings. Sometimes, when an air pollutant, such as sulfuric acid combines with the water droplets that make up clouds, the water droplets become acidic, forming acid rain. When acid rain falls over an area, it can kill trees and harm animals, fish, and other wildlife.
Acid rain destroys the leaves of plants.When acid rain infiltrates into soils, it changes the chemistry of the soil making it unfit for many living things that rely on soil as a habitat or for nutrition. Acid rain also changes the chemistry of the lakes and streams that the rainwater flows into, harming fish and other aquatic life.
Next is eutrophication.Rain can carry and deposit the Nitrogen in some pollutants on rivers and soils. This will adversely affect the nutrients in the soil and water bodies. This can result in algae growth in lakes and water bodies, and make conditions for other living organism harmful.
Besides, ground-level ozone also one of the air polution effect.Chemical reactions involving air pollutants create a poisonous gas ozone (O3). Gas Ozone can affect people’s health and can damage vegetation types and some animal life too.
Air pollutants can be in the form of particulate matter which can be very harmful to our health. The level of effect usually depends on the length of time of exposure, as well the kind and concentration of chemicals and particles exposed to. Short-term effects include irritation to the eyes, nose and throat, and upper respiratory infections such as bronchitis and pneumonia. Others include headaches, nausea, and allergic reactions. Short-term air pollution can aggravate the medical conditions of individuals with asthma and emphysema. Long-term health effects can include chronic respiratory disease, lung cancer, heart disease, and even damage to the brain, nerves, liver, or kidneys. Continual exposure to air pollution affects the lungs of growing children and may aggravate or complicate medical conditions in the elderly.
Solution to reduce air pollution
Solution efforts on pollution is always a big problem. This is why prevention interventions are always a better way of controlling air pollution. These prevention methods can either come from government or by individual actions. In many big cities, monitoring equipment have been installed at many points in the city. Authorities read them regularly to check the quality of air.
Governments throughout the world have already taken action against air pollution by introducing green energy. Some governments are investing in wind energy and solar energy, as well as other renewable energy, to minimize burning of fossil fuels, which cause heavy air pollution.Governments are also forcing companies to be more responsible with their manufacturing activities, so that even though they still cause pollution, they are a lot controlled.Car manufacturing companies are also building more energy efficient cars, which pollute less than before.
First of all we need to practice to use public transportation. We need to encourage yourself to use more and more public transportation to reduce pollution. Besides, try to make use car pooling. If you and your friend, neighbor and family go to the same place and have same timings you can explore this option to save energy and money. These may reduce the gas release from the car exhaust.
Next, conserve the energy. Switch off fans and lights when you are going out. Because large amount of fossil fuels are burnt to produce electricity. You can save the environment by reducing the amount of fossil fuels to be burned if you conserve the energy. Use energy (light, water, boiler, kettle and fire woods) wisely. This is because lots of fossil fuels are burned to generate electricity, and so if we can cut down the use, we will also cut down the amount of pollution we create.
Besides, understand the concept of Reduce, Reuse and Recycle. Do not burn your items that you not need anymore. Because you can reuse them for some other purpose. Recycle and re-use things. This will minimize the dependence of producing new things. Remember manufacturing industries create a lot of pollution, so if we can re-use things like shopping plastic bags, clothing, paper and bottles, it can help.
